javascript - 从 Javascript 数组中获取 n 个值

Question

我正在尝试遍历 JavaScript 数组并将单个对象值显示为警报。基本上，该数组包含 person

类型的对象

"person" : {
     "id": String,
     "name": String,
     "address": String
}

我的数组如下:

//This is where I get my array from the code behind. It's not empty. I checked
var obj = JSON.parse(val)

obj.forEach(function (entry) {
    console.log(entry);
    //This prints the entire array and its objects
});

我要的不是打印整个数组，我要打印:

obj.forEach(function (entry) {
    console.log(entry[1].name);
    console.log(entry[1].address);
    //This prints the entire array and its objects
});

我应该对我的代码进行哪些更改？

在foreach里面，entry只是一个person元素，使用:

obj.forEach(function (entry) {
        console.log(entry.name);
        console.log(entry.address);
});
